Will this bolt directly to my factory mounting points?

Yes. This exhaust connects at the catalytic converter flange and exits at the factory rear bumper location — standard OEM bolt-up. You'll need basic hand tools and jack stands.

Do I need a tune after installing this?

No. The catalytic converter remains stock, so there's no emissions system change. The tune-less install is one of the main advantages of a catback-only system.

Does stainless steel need any prep or sealant before install?

Stainless steel is ready to bolt on as-is. Clean the mounting flanges with a wire brush to remove any factory residue, then use a new gasket kit at the catalytic converter connection point — standard practice for any exhaust install.
